The accident occurred around 9 p.m. in the 1800 block of Lake Bluff Lane when the young driver drove around an undeveloped subdivision with the 13-year-old boy on top of his car, according to the Daily Herald.

The driver reportedly braked sharply, causing his brother to fly off the hood and hit his head before the car came to a stop on his chest, police said.

Police arrived to find the young boy with multiple injuries and was flown from the scene to Advocate Lutheran General Hospital in Park Ridge in critical condition, the Daily Herald reported.

The driver, whose name is not being released because he is a juvenile, did not have a license and was reportedly driving under a valid learner’s permit.

Pingree Grove Police are still investigating the incident and charges are pending the young boy’s condition, but at a minimum the driver will face driving without a license, the Daily Herald reports.
